Max Blazer drop?

[70k52wd]

I can't seem to find the info I'm looking for...How low of a drop can be done before getting into frame mods...And I was at the wheel tire fitment, I like the 20's, 22's look (R1, Bama). Can I achieve this combo/look without cutting frame? If not, at max drop, what would be proper wheel/tire combo? One more question...I have Chisholm 2in lower control arm, can a bag system work with that, or do I need to return OE arms...Is there any benefit of a bag system over static if you only plan on a drop without frame mods? And where on earth do you hide all the bag system stuff on a blazer(pumps/tanks etc)???
